Pipe tongs for the installation of metal structures

In the modern market metal-plastic pipes can be safely called the most demanded material for the installation of plumbing household systems. In addition to excellent performance characteristics, this type of construction is quite easily and quickly mounted, but for its high-quality assembly you will need a specialized tool, the main representative of which are pipe tongs.

Why do you need ticks

Installation of this type of waterworks is carried out using a whole set of node fittings, united by the common name fittings for sewer systems.

These parts can be of 2 types:

• The first and oldest method is a threaded connection.. Everything is quite simple here - a split sealing ring is installed on the pipe and tightened with a nut. On the one hand, you only need a set of keys. But on the other hand, this connection weakens with time and requires revision, which makes such installation in a concrete screed impossible.
• Press fitting is considered more modern and reliable.. It consists of a fitting with o-rings, an insulating ring and a crimp metal sleeve. The press fitting is put on a pipe for sewage or heating and crimped under high pressure. It is for this basic operation that the press pliers are needed for crimping metal-plastic pipes.

Experts agree on the fact that crimping is much safer and more durable. These structures can withstand more pressure, are mounted faster and most importantly do not require further monitoring, which makes it possible to place them behind the gypsum cardboard false panels or to mount them in a concrete screed.

Tool types

With the assortment that the modern market offers, it is difficult for an inexperienced person to figure out what kind of tool it is better for him to take and whether it is worth paying a heavy price for any particular model.

Hand tool

Manual press pincers for metalplastic pipes are the most widespread version of this direction. As the name implies, their work is based on the use of muscular strength. For their operation does not require professional skills and the price is quite acceptable here.

But manual pipe pliers can only be used for mounting systems with a small diameter of up to 26 mm; they are not designed for a large section. Another serious limitation here is the impressive size. In order to create the necessary effort, a large lever is required, therefore the handles of this tool must be long and it is not convenient to work with such tongs everywhere.

Specialized power tool

Professional specialized tools are always quite expensive. The line here is quite wide, ranging from the use of hydraulics and ending with an electronic programmable drive, having in its configuration a lot of different sensors.

Professional pliers for crimping metal-plastic pipes can afford construction organizations that perform large volumes of work. As a rule, they require a stationary power supply and certain skills in work. For individual use, it is impractical to buy them.

Pressing guns

Practically everyone is familiar with such a useful device as a screwdriver. Crimp pliers for metal-plastic pipes are now created on the same base. The unit has a comfortable pistol grip and a battery-powered electric drive.

If we talk about the exploitation at the household level with their own hands, then this is almost an ideal tool. It does not require much physical effort and even a child is able to work with it.

Plus, this gun can be used in wet areas without fear of electric shock. In addition, having small overall dimensions, it can be used in confined spaces and difficult conditions.

It is important: if the tool is of high quality, then it is absolutely unimportant which of the above modifications you will use, all of them will perform their task equally well.

What to look for

Despite the relatively simple design, the press pliers for crimping metal-plastic pipes must be selected according to certain criteria.

• First of all, you should pay attention to the maximum diameter of pipes with which the presented model is capable of working. This data contains instruction manual. It is noteworthy that if your pipes have a diameter less than that specified in the passport, you can use the special inserts that come in the kit.

Tip: in our great country, everything is regulated by state standards. Abroad there is no single metric system, and materials from different manufacturers may not match. Therefore, when buying ticks, take a pipe sample with you or buy all the material from one manufacturer.

• Although the tool is quite simple, in some models additional functions may be provided in order not to re-read the entire instruction, pay attention to the marking.
• APC - this abbreviation means that there is an automatic control over the crimping process. In other words, until you finish the action, the tool will not open.
• APS - this system is responsible for uniform crimping depending on the section of the fitting.
• OPS - this designation indicates the presence of a stepped lock, which allows you to greatly facilitate the process of compression.
• You should also pay attention to the name of the manufacturer, in our century of total fraud is easy to make a mistake and buy a fake. Sometimes it is better to take unpretentious mites from a well-known company than a seemingly elegant unit of unknown production. The most innocent thing here is a breakdown of the fixture itself, worse if you find a poor-quality crimp after pouring the screed.

Crimping technology

As mentioned earlier, working with this tool is extremely simple. Initially, you need to smoothly trim the edge of the pipe. After that the chamfer is removed by the calibrator and the cut is processed. Next, the pipe is put on the fitting, until it stops.

There is a hole in the crimp sleeve through which the density of the nozzle is controlled. Everything, it is possible to use pincers for compression of metalplastic pipes.

The video in this article shows all the crimp technology in detail.

Conclusion

Working with this tool is not difficult, but it is a pity to invest money in a thing that you will use once. In this regard, I would like to give advice if you are buying all the material in a large building supermarket, ask, in such centers there is often a tool rental. And when buying a large amount, it is sometimes free.
